Benefits of technology

[0008]An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following aspects.

Problems solved by technology

However, the head mounted display device has a peculiar function of allowing a user to visually recognize a preview image as a virtual image superposed on an outside scenery, and the following problems have been pointed out.
Further, image data of the imaged image is subjected to various kinds of data processing relating to virtual image formation, and the outside scenery of the virtual image as the imaged image is provided with a delay.
As a result, mismatch may occur between the outside scenery provided as the virtual image and the real outside scenery and give a feeling of strangeness to the user.
Even when the camera image imaged in the still image imaging mode mismatches with the outside scenery visually recognized by the user, the image is the still image desired by the user and imaged, and the user knows the feeling of strangeness due to the mismatch with the real outside scenery and is harder to have the feeling of strangeness.
According to the configuration, even when the preview image is displayed, the display time is limited to an initial predetermined time, and thereby, the time in which the feeling of strangeness can be given may be limited.

A. Embodiment

A-1. Configuration of Head Mounted Display Device:

[0033]FIG. 1 is an explanatory diagram showing a schematic configuration of a head mounted display device in one embodiment of the invention. The head mounted display device 100 is a display device worn on a head and also called a head mounted display (hereinafter, “head mounted display 100”). The head mounted display 100 of the embodiment is an optically-transmissive head mounted display device that enables visual recognition of a virtual image and direct visual recognition of outside scenery.

[0034]The head mounted display 100 includes an image display unit 20 allows the user to visually recognize a virtual image when worn on a head of a user, and a control unit (controller) 10 that controls the image display unit 20.

[0035]The image display unit 20 is a wearable unit worn on the head of the user and has a spectacle shape in the embodiment. The image display unit 20 includes a right holding part 21, a right display drive...

modified example 1

[0074]In the above described embodiment, the configuration of the head mounted display is exemplified. However, the configuration of the head mounted display may be arbitrarily determined without departing from the scope of the invention. For example, addition, deletion, conversion, etc. of the respective configuration parts may be made.

[0075]The assignment of the component elements to the control unit and the image display unit in the above described embodiment is just an example, and various forms may be employed. For example, the forms are as follows: (i) a form in which the processing functions of the CPU, the memory, etc. are provided in the control unit and only the display function is provided in the image display unit; (ii) a form in which the processing functions of the CPU, the memory, etc. are provided in both the control unit and the image display unit; (iii) a form in which the control unit and the image display unit are integrated (e.g., a form that functions as a spec...

Abstract

A head mounted display sets a display status by a user via a display status setting table for virtual display of a virtual image corresponding to an imaged image imaged by a camera (real image) as a camera preview. Then, image data necessary for virtual display of the camera preview in response to the set display status is formed, and the camera preview is virtually displayed in a virtual image display range in the set display status.

Description

BACKGROUND[0001]1. Technical Field[0002]The present invention relates to a head mounted display device.[0003]2. Related Art[0004]Head mounted display devices (head mounted displays, HMDs) as display devices worn on heads have been known. For example, the head mounted display device generates image light representing an image using a liquid crystal display and a light source, guides the generated image light to an eye of a user using a projection optical system, a light guide plate, etc. and thereby, allows the user to visually recognize a virtual image (for example, Patent Document 1 (JP-A-2013-178639)). In the Patent Document, a technique of realizing augmented reality (AR) for additionally presenting information to a reality environment using a computer is applied, however, not limited to the application of AR. In a head mounted display device with a camera, for a user to visually recognize a virtual image superimposed on an outside scenery, an imaged image imaged by the camera ma...
